The biggest feature of the self-taught high number is that the questions are basically fixed, which means that the real questions over the years are very important; It's basically those kinds of problems. As long as the questions in the real questions over the years are clarified, you can basically pass the exam. However, one thing is that line generation calculation is more complicated, so you'd better be skilled, otherwise the exam will be tense.

Personal advice, if time is loose, read books and do after-school exercises in various chapters; You can put this part down. Then chew the real questions over the years and finally do several sets of simulation questions. Usually this set of 80 points is not a problem. If time is tight, go straight to the real question. If you can't do it, look at the answers in the corresponding chapters of the textbook and find out the real questions. However, the disadvantage of doing this is that you are not skilled in doing the questions during the exam. Although you know the steps, the process is easy to make mistakes, and it is no problem to pass the exam.

Self-taught exams should be based on real questions, and general exams are simpler than textbooks. In addition, it is enough to look at the examples in the textbook, and it is not necessary to look at the introduction of theorem inference from the beginning.

Of course I have to read books, mainly examples! Understand every question. If you have time, do exercise books, if possible! If you have an answer, don't do it without an answer! Buy 10 sets of test papers half a month before the exam. When you do it, you will find that the topic is very fixed. It's almost over when you're done.
